Eduardo, is the libvirtd daemon necessary for libvirt-based to
manage the PowerVM node? I guess so,
if it's the case, then what's the environment in the PowerVM-based
node to run the libvirtd daemon, is it vios?
Dennis,

libvirtd isn't necessary to manage LPARs. You just need to run virsh in
your own computer in order to connect to an HMC/VIOS or IVM environment.

Any questions please feel free to ask.

Eduardo,

Thanks for the help! I encounter an issue when trying to connect the remote VIOS/IVM server:

1. The used virsh is built from 0.9.12 source code with ./configure --prefix=/usr --with-phyp; make; make install;

2. When I try to connect the VIOS server with ssh, it succeeds with output looks like:
    root dennis-:/home/libvirt-0.9.12# ssh padmin 10 30 56 60
    padmin 172 30 56 60's password:
Last unsuccessful login: Wed Jul 4 21:22:22 CDT 2012 on ssh from 10.16.10.94
    Last login: Wed Jul  4 21:23:14 CDT 2012 on /dev/pts/1 from 10.16.10.94
    [vios:/home/padmin]

3. My virsh runs in the local ubuntu 12.04 system, and I've executed the following command:
    sudo usermod -G libvirtd -a padmin

4. When I try connect the VIOS server with virsh, issue occurs:

    root dennis-:/home/libvirt-0.9.12# virsh -c phyp://padmin 10 30 56 60
    Enter padmin's password for 10.30.56.60:
    error: An error occurred, but the cause is unknown
    error: failed to connect to the hypervisor

root dennis-:/home/libvirt-0.9.12# virsh -c phyp+ssh://padmin 10 30 56 60
    padmin 10 30 56 60's password:
error: End of file while reading data: bash: sh: command not found: Input/output error
    error: failed to connect to the hypervisor

    some times the last command also shows error message like:
root dennis-:/home/libvirt-0.9.12# virsh -c phyp+ssh://padmin 10 30 56 60
    padmin 10 30 56 60's password:
error: Cannot recv data: bash: sh: command not found: Connection reset by peer
    error: failed to connect to the hypervisor

Is there any tips about this?

BRs,
Dennis
